LocoMoTlvE-TANK.

SPECIFICATION forming part of Letters Patent No. 431,397, dated .Tuly 1, 1890.

Application filed February 19, 1890. Serial No. 341,015. (No model.)

To @ZZ whom it may concern:

Be it known that I, THOMAS W. RANsoN, of Hornellsville, in the county of Steuben and State of New York, have invented certain new and useful Improvements in Locomotive- Tanks; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as Wi 1l enable others skilled in the art to which it pertains to make and use the same.

My invention relates to improvement in locomotive-tanks; and it consists in certain features of construction and in combination of parts hereinafter described, and pointed out in the claim.

Heretoforein the con struction of ordinary locomotive-tanks the external and internal side walls of the tank were vertical, whereby was had broad flat surfaces on top of the legs of the tank. Usually an upwardly-projecting rim extended along the sides and across at the rear of the coal-space for increasing the latter. On these fiat surfaces inside the rim the coal dust and cinders accumulated, and as these were damped from exposure to the weather and from other causes ythe result was that the top of the tender soon rusted out and had frequently to be renewed. As an improvement I have devised the locomotive-tank illustrated in the accompanying drawings.

Figure l is a side elevation in section through the center ofA the tank. Fig. 2 is a plan. Fig. 3 is a front end elevation, partly in section. Fig. 4 is a plan of the forward portion of the tank, showing a modification.

A A and A are the outside walls of the tank, and B B and B are the internal sloping walls thereof.l The outer walls, as with an ordinary tank,are approximately vertical, and as my intention is not to decrease the water-space of the tank the width of the water-space at the bottom of the legs is increased inversely as the width is decreased at the top of the legs. The upper edge of walls A A are flanged inward on a curve at b to join the top edges of the sloping walls B B, and rim C, along the sides thereof, is at the union of plates A and B, and the lateral or central member of the rim is located at the union of wall B with the top wall D; hence there is no ledge or flat surface inside the rim for the lodgment. of dust, dirt, or cinders. The top wall D, back of the rim, is provided with a iilling-nozzle d, and this top plate is easily kept clean; in fact, is likely to be washed off infilling the tank. Outside the coal-space there is no difficulty in keeping the exposed surfaces clean and well painted, and thus protected from rusting; but where the coal comes in contact with the tank paint would be soon worn oif, and consequently would give little or no protection as against rusting. If rim O were omitted, as would likely be the case where only short runs were made, requiring but a small amount of coal, there still would be no fiat surface exposed that would come in contact with the coal. The rounded edges h would not retain dirt or dust, and, besides, these rounded surfaces. as they do not engage the coal, can be kept clean and well painted. With the hopper-shaped coal-box thus provided the coal gravitates to a narrow space along the internal bottom of the tank, where it is more convenient for the fireman than if it were spread over a broader surface, as in the case of an ordinary tank.

A modification is shown in shown in Fig. 4,

where the vertical walls a are omitted, and' in place thereof the internal sloping side walls B B are extended to the front of the tank, thereby cutting the rounded forward end sections a CL obliquely, as shown by dotted line t' c', Fig. 3. Either construction may be employed, according to circumstances.

Vhat I claim is- A locomotive-tank having internal sloping walls which constitute the sides and end or ends of an inclosed hopper-shaped coal-box or other receptacle, substantially as set forth. In testimony whereof I sign this specifica tion, in the presence of two witnesses, this 5th day of February, 1890.
